UPPER-FORMING MACHINE.

Application filed April 3,

To all w item it may concern:

Be it known that 1, PAUL BEIER, engineer, a citizen of the Free State ofBaden, residing in Karlsruhe, Jollystrasse 9, Germany, have inventedcertain Improvements in Upper- Forming Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings inclicatinglike parts in the several figures.

This invention relates to machines for forming or shaping the endportions of the uppers of boots and shoes and is herein shown asembodied in a machine for shaping or molding the heel end of astitchdown shoe upper and forming thereon an outturned sole attachingflange.

A general object of the present inven tion is to provide an'improvedmachine for this work which will be simple in construction and moreeffective in operation than prior machines.

A feature of the invention consists in the combination with heel endmolding or 'sl'iaping means for a shoe upper arranged to leave amarginal portion projecting outside said shaping means, of flangeforming means comprising members which, as shown, are firstseparated toturn outwardly the side portions of the projecting margin and are thenmoved bodily to turn outwardly the rear portion of the projectingmargin.

A further feature of the invention consists in the combination withmolds for shaping the rear portion of a shoe upper, of a pair of flangeforming members which are pivoted outside of the area enclosed by therear portion of the upper, as at the rear of the molds, and areseparated at their front ends to act upon the projecting margin indirections substantially normal to the margin. Since the inner mold ofthe molding means diminishes in lateral extent from front to rear of theupper and the illustrated pivot of the members is at the rear of theupper, the lateral movement of the members at various portions of theirlength is substantially proportional to the lateral extent of the innermold and substantially normal to the side portions of the pro- 'jectingmargin throughout their extent.

Another feature of the invention consists in means for varying themovement of separation-of the flange forming members to adapt them forco-operation with molds of 1920. Serial 1T0. 371,132.

different widths. After the described separative movement of the flangeforming members they are given a movement of translation to cause themto engage and turn outwardly the portion of the projecting margin at therear end of the molds.

A further feature of the invention consists in means for varying thebodily movement of the flange forming means to adapt the machine foroperation upon the flanges of uppers held by molds of different length.

Still another feature of the invention consists in means for acting uponthe upper at the center of the rear portion of the upper in the gap oropening, occasioned by the separative movement of the flange formingmembers about their pivot, to press the up per at this point against theouter mold.

Another feature of the invention consists in means for positivelypressing the flange forming members upon the outturned flange v to holdit against the top face of the outer mold of the heel end molding meanswith a uniform pressure throughout the extent of the flange; Preferablyand as shown, the carrier forthe flange forming members is so mountedthat the members have universal movement and may adapt themselves to theplane of the flangeirrespectively of the variations in thickness ofdifferent portions of the flange.

In order that the relation of the flange forming members to the moldsshall not vary when molds of different height are used in the machine,it is important that the positively moved flange forming means have avariable movement of approach to the mold perpendicularly to thedirection in, which the flange forming means acts in turning out theprojecting margin. Accordingly, a further feature of the inventionconsists in means for varying the limit of approach of the flangeforming means to the molds in the flange pressing opera tion to adapt itfor operation upon molds of different height.

These and other features of the invention including certain details ofconstruction and combinations of parts will appear more fully from thefollowing description when read in connection with the accompanyingdrawings and will be pointed out in the appended claims.

and

Fig. 8 is a plan view of the flange forming means in the position shownin Fig. 7.

Referring to Fig. l, the numeral indicates the column of the machine towhich is bolted the frame 4 of the head by which all the operating partsare carried. The frame 4 has rearwardly extending brackets 6 in which acam shaft 8 is journaled. A drive wheel 10 is loose on the shaft 8 andis formed with a female friction cone cooperating with a male cone l2pinned to the shaft 8. A wedge 14 is operated in a manner to bedescribed to force the hub of the drive wheel 10 outwardly to bring thefriction cones into engagement and when the wedge is reversely moved aspring 16 forces the friction cones out of engagement and allows themachine to stop.

The wedge 14 is operated by a treadle rod 18 connected to a foot treadle(not shown) and is raised by a spring 19. On the upper end of thetreadle rod is a member 20 forming part of the wedge 14 (Fig. 2) andmounted for vertical movement on the shaft The member 20 is connected bya link 22 with one arm 24 of an angle lever pivoted at 25 to a portionof one of the brackets 6, the other arm of the lever being indicated bythe numeral 26. The length of the link 22 is adjustable and also isconnected to the arm 24 by mechanism comprising an eccentric operated bya handle for conveniently varying the relation of the arm 24 to thewedge 14 for a purpose which will appear. The arm 26 carries a roll 32normally lying in a depression 35 in a cam 84, being swung out ofthedepression when the wedge 14 is depressed by reason of the connection 22to the arm 24. As soon asthe machine starts the cam 34 holds the roll 32away from the axis of the cam and, of course, holds the wedge 14 inclutch closing position. The machine, therefore, will remain inoperation until another depression 37 in the cam 34 reaches the roll 32,whereupon the roll on ters the depression and allows the wedge 14 torise and the machine to stop. Since the cam 34 has two depressions 35,37 the machine stops not only at the end of the cycle but also at apoint in the cycle after the mamechanism. On the arm 26 is pivoted at 39a brake shoe 86 which engages a brake disk 38 when the roll 32 reaches adepression in the cam 34 and quickly stops the machine. The roll 32 isadjustably held on the end of the arm 26 so that adjustment may be madeto vary the action of the brake shoe, and the handle 30 may be operatedand the length of the link 22 adjusted to vary the movement of the wedge14 and hence the pressure on the clutching surfaces under differentworking conditions.

An interchangeable inner or male mold is held by a screw 52 upon a slide54 which is mounted for horizontal movement in the frame 4. A sleeve 56is j'ournaled at 57 on the slide 54 and through the sleeve 56 passesfreely an operating rod 58 which carries a stop nut 60 on one side ofthe sleeve and a spring 61 abutting against an adjustable nut 62 on theother side. The rod 58 is pivoted at its inner end to the upper end of alever 66 fulcrumed to the frame 4 at 68 and carrying between its ends acam roll 70 which lies in a cam path formed in the inner face of a camblock 72. The cam 72 acts through the spring 61 to draw the inner mold50 into an outer mold 74 and to shape the upper material placed aboutthe inner mold to the form of the rear portion of a shoe. The inner mold50 is preferably heated to cause'the molded material to set more quicklyin its molded shape and the heating means is preferably electrical, aheating unit 75 being insertedin a space formed in the mold 50. Theterminals for connection of the electric current to the unit 75 areindicated at 76.

For forming the marginal portion of the upper material projecting abovethe molds 50, 74, into an outturned flange the following mechanism isprovided, A sliding sleeve is mounted for vertical movement in the frame4. In order to permit the ball 82 to be assembled within the sleeve 80the sleeve is preferably made in two parts. Inside the sliding sleeve isa ball 82 which engages a spherical formation on the inner walls of thesliding sleeve. The ball 82 has a threaded stem 84 which passes througha sleeve 86, journaled on the end of a lever 88. Nuts 90 on the sleeve84 above and below the sleeve 86 provide for vertical adjustment of thesliding sleeve 80. The lever 88 is fulcrumed at 92 to the frame 4 andits rear end is pivoted to a bar 94 which has its lower end slotted toembrace the shaft 8 and slide vertically thereon. On the bar Saris a camroll 96 lying in a cam path formed in the the flanges 100 so that theslide carrier will.

be raised by upward movement of the sliding sleeve 80. Beneath the ball82 the slide carrier 102 has a projection 106 with a sphericaldepression in its top face (Fig. 1) to be engaged by the lower surfaceof the ball 82 when the slide carrier is held from downward movement,there being a space between the flange 100 and the top face of the slidecarrier 102 providing a small amount of lost motion between the parts toallow the lower face of the ball 82 to seat in the spherical depressionin the projection 106 when downward movement of the carrier is arrested.

in the slide carrier 102 is mounted a slide 110. The slide 110 isconnected at its rear end to one end of an adjustable link 114 the otherend of which is pivoted to a lever 116 fulcrumed at 118 to the frame l.The lever 116 has its lower end bifurcated to embrace the slotted upperend of a lever 120 and between the bifurcations is mounted a roll 117lying, in the slot of the lever 120.

The lever 120 is fulcrumed to the frame at 121 and, between its ends,carries a cam roll 122 which engages a cam path in acam block 12 1 onthe shaft 8. end of the lever 116 has a plurality of holes at differentdistances from its fulcrum and a pin 126 which carries the roll 117 maybe placed in either one of the holes and through the roll and theslotted upper end of the lever 120. By changing the location of the roll117 the amount of movement communicated by the cam 12 1 to the slide 110may be varied. The levers 116 120 constitute a compound lever fortransmitting motion from the cam 1% to the slide 110.

Below the slide 110 another slide 130 is mounted in the slide carrier102 for movement in the same direction as the slide 110. To the rear endof the slide 130 are pivoted two flange formers or wipers 132, 1841 by apin 186 which passes through the slide 130 into a slot 137 formed in theslide 110 (Fig. 5). The wipers have on their inner edges projections138, 139 which overlap when the wipers are closed (Fig. at) and haverearwardly inclined faces 140, 1&1 arranged to be engaged by a roll 1 12on a pin 1&4 which passes through aslot 145 in the slide 130 and isfixed in the slide 110 (Fig.

The bifurcated 6). The slide 130 is held forward relatively.

to the slide carrier 102 by springs 150 (Fig. 1) which have their rearends attached to the slide 130 by pins 151 and extend forwardly throughholes in the slide carrier 102, their front ends being fastened to thecarrier by pins 153.

When the slide 110 is moved rearwardly by the operative connectionsdescribed the slide 130 remains stationary by reason of the tension ofthe springs 150 and the roll 1 12 engages the inclined faces 14:0, 141of the wipers and causes them to open (Fig. 6). When the wipers haveopened to the degree desired for the given shoe upper their front endsengage screws 156 (Fig. 2) which are threaded through downwardprojections 158 from the slide carrier 102 and are adjusted properly tolimit the outward swing of the forward end of the wipers in accordancewith the size of the mold. The wipers 138,-

139 are moved to closed position by grasshopper springs 160 each ofwhich is coiled around a screw 162 and'has one end resting against anouter face of a wiper and the other end resting against one of theprojections 158 (Fig. 1). The pivot pin 136 is located at a point to therear and outside of the molds and as a result the opening movement ofthe front ends of the wipers is jecting margin which they engage. Thefact that the wipers are pivoted at the rear of their acting facescauses the portions of the acting faces which engage the upper at therear to separate when the forward ends of the wipers are swun outwardly.To fill the gapthus formed a projection or part 166 is provided on theslide 130 which engages the upper at the rear between the 'wipers andforces it into engagement with the mold 7 1 (Fig. 7). After the slide110 has moved rearwardly far enough to effect the desired separation ofthe flange turning means or wipers 132, 134-, and their further movementhas been limited by the screws 156, or if the screws are set widelyapart, by engagement of the pin 136 with the forward end of the slot 137further movement of the slide 110 effects bodily movement of the wiperto turn outwardly the upwardly projecting margin at the rear of the shoe(Fig. '7). This movement causes the projection 166 to turn outwardly theportion of the upper between the separated wipers. The wipers are thendepressed, as shown in Fig. 7, to over-mold the flange and apply ironingpressure thereto between the inclined surfaces 170, 172.

The operation of the machine is as follows: In the position of themachine shown in Figs. 1 and 2 the upper has been operated upon and themachine is about to stop. The drive wheel 10 is rotating in thedirection of the arrow (Fig. 1) the wipers have been substantiallynormal to the face of the proreturned to their forward and closedposition, and the upper is about to be released by a forward movement ofthe male mold 50. The machine will stop when the depression 35 of thecam 34 reaches the roll 32, causing the wedge 14 to he raised and thebrake 36 to be applied. The molded upper will then be removed andanother unmolded upper placed over the male mold 50 with its marginalportions extending above the molds 50, 74, as shown in dotted lines inFig. 1. The treadle rod 18 will then be operated to start the machine.The male mold 50 will be drawn by the action of the cam '7 2 into thefemale mold '74 and cause the upper to be shaped to correspond to thesides and end of the rear portion of a shoe, the spring 61 providing forvariations in the thickness of the upper and also variations in the sizeof the molds. The cam 98 next operates to lower the sleeve 80 andconnected parts until the wipers 132,134 rest against the top face ofthe male mold 50 and then farther until the lower surface of the ball 82rests in the spherical depression in the projection 106, this beingpermitted by the lost motion provided by the space between the flanges100 and the top face of the slide carrier 102. The carrier is,therefore, capable of limited universal movement. After this preliminary movement of the wipers is effected the cam 124 acts to moverearwardly the slide 110, causing the roll 142 to engage the inclinedfaces 140, 141 of the wipers and move their'front ends outwardly to laythe upper over the top face of the female mold 74. After the wipers havefully opened and their front ends have engaged the screws 156 relativemovement between the slides 110, 130 ceases and both move together tocause the Wipers to fold outwardly the end portion of the upper marginover the rear end of the mold '74. At this point in the operation aformation of the cam 98 acts on the roll 96 to further depress thewipers positively against the outwardly turned margin of the upper.

The wipers have downwardly and outwardly inclined faces 170 (Fi 7) whichco-operate with corresponding downwardly and outwardly inclined faces172 on the mold 74. As the wipers are positively pressed fartherdownwardly these faces co operate to form the outturned flange of theupper into a downwardly and outwardly directed flange and to iron downthe flange.

Since the slide carrier 102 and the wipers are able to rock in anydirection, differences in thickness of different portions of the leatheracted upon by the wipers is taken care of and equal bearing of thewipers on all portions of the flange formed as the wipers forceoutwardly the margin of, upper extending above the molds 50, 74 isensured. It is only neecssary of course that the flange project at rightangles to the side of the last but the over-molding effected by thismachine ensures that the molded flange will not go back or react afterremoval from the mold, beyond the desired position at right angles tothe side of the shoe.

The second depression 37 in the cam 34 has now reached the roll 32 andthe machine stops with the'upperand flange under molding pressure whereit should remain for a time to allow the material-to set in moldedcondition. To expedite this setting the wipers are preferably heated. Inthe construction herein shown this is efliected by electrical heatingunits 167 inserted in spaces provided in the slide carrier 102 andconnected in series, the terminals for'making the electrical connectionsbeing indicated at 168. The machines are preferably arranged in pairs sothat one machine may be allowed to remain stopped with an upper thereinwhile an upper is being placed in the other machine and the machinestarted. After allowing the machine to remain at rest for a suitablelength of time it is again started and stops automatically with theupper released.
